Application filed. December 5, 1925, Serial No. 73,395, and Great Britain March 4, 1921.

This invention relates to captive caps or closures for scent sprays, collapsible tubes and the like.

According to the present invention a cap or closure is attached to the scent spray, collapsibie tube or he like by a spring member of which the ends are sprung apart in such a manner that when the cap is completely unscrewed from a screw threaded top having a hole therein, the cap is caused-t0 spring automati ally away from the top and expose the opening therein. The ends of the spring are spread apart by being passed through spaced holes provided in the screw threaded top or in the top of the container, and are then fastened, preferably by looping over the free ends. The spring member is formed of wire bent in such a manner as to i'orni a loop at one end which is adapted to be rotatably attached to the cap. The looped end of the spring may either be fitted to a. pin at the top of the cap or it may be fitted either directly or by being attached to a plate into an upwardly extending rim which is adapted to be spun inwardly so as to form a recess.

The invention will now be described wi h reference to the accompanying drawings, wherein Figure 1 shows the invention applied to the stopper oi a scent spray.

Figure 2 shows a modification of the arrangement shown in Figure 1.

Figure 3 shows the invention applied to a collapsible tube with a modified form of attachment of the spring member of the cap.

Figure 4c shows a plan of Figure 3.

Figure 5 shows a modification oi F 4.

Figure 6 shows a t'urther modification applied to a collapsible tube.

Figures 7, 8 and 9 show details.

Referring first to Figure 1 the stopper for a scent spray is fitted with a cork 1 adapted to engage with the scent bottle and having a screwed extension 2 closed by a screwed cap 3. The top of this cap has an upwardly extending rim 4 which is spun inwardly as shown at 5 so as to form a recess. A spring member 6 is bent so as to form two limbs 7 and 8 (Fig. 7) forming a loop 9 which is sprung into the recess thus formed and -freely engages therewith so as to enable the cap 3 to be screwed onto or unscrewed from the screwed extension 2.

The free ends of the limbs 7 and 8 are spread apart and are each passed through holes formed in a rim 10 01" the stopper and then looped over as indicated at 11. As shown the rim is slightly raised so that the spring ends will pass diagonally therethrough.

Instead of forming the spring member 6 with a loop it may be attached to a. disc 1i over which the upwardly extei'iding rim 5 on the cap is spun so as to hold the disc rerolubly in position as shown in Figure The loop of the spring may be fitted over a. pin 12 projecting from the cap 3 as shown in Figures 3 and (S or may be engaged by spinning the rim 4 outwardly as indicat d 13 in Figure 8.

In Figures 3 to 6 the invention is shown as applied to a collapsible container for tooth paste and the like and in Figures 3 and i the ends of the spring member 6 are passed throu h luo's or e es 1 liormed inte 'ral t: O I) with the top of the container. In F igure l the ends of the spring member are turned inwardly so as to engage with the lugs or eyes 14 whereas in Figure 5 they are turned outwardly before the ends of the limbs are looped over to engage with the lugs or eyes 14?.

In Figure 6 a rim 15 is provided around the top of the collapsible container and is arranged in substantially the same manner as the rim 10 in Figure 1.

In all the constructions above described the ends of the spring member are spread apart sons to produce a spring action whereby the cap when completely unscrewed from the stopper is automatically caused to spring 1 away from the ends of the stopper and thus expose the opening therein.

In addition to scent sprays and collapsible containers for tooth paste and the like the invention may also be applied to other containers having a cap which it is desired to attach thereto so as to prevent it from being lost while permitting of the cap to be freely rotated for the purpose of moving it into its closing position or for the purpose of removing it for the purpose of exposing the aperture which is closed thereby.

In all the constructions above described the ends of the spring member are spread apart and the free ends engage with spaced holes, the plane of the holes being difierent to the direction of the limbs 01 the bifurcated spring member so that when the cap is in the closed position the bifurcated ends of the spring member will be under strain and when the cap is completely unscrewed from the stopper the looped ends of the spring member move to a free position to relieve the strain and cause the cap to spring automatically away from the end of the stopper and thus expose the opening therein.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is 1. In combination with a captive cap or closure and container upon which the cap is adapted to be screwed, of a bifurcated spring member rotatably secured to the cap, and anchoring means connected to the container, the free ends of the bifurcated spring mem ber engaging said anchoring means, the engagement of the free ends of the spring member with the anchoring means being such that the limbs of the bifurcated spring member are sprung apart under strain when the cap is screwed on the container, and when the captive cap is completely unscrewed from the container the limbs, tending to return to their unstrained position cause the cap to spring automatically from the container.

2. In combination with a captive cap or closure and container upon which the cap is adapted to be screwed, of a bifurcated spring member rotatably secured to the cap, and anchoring means connected to said container, said anchoring means having spaced holes therein, the free ends of the bifurcated spring member being engaged with said holes whereby the limbs of the bifurcated spring member are sprung apart under strain so that when the cap is completely unscrewed from the container, the limbs, tending to return to their unstrained position, cause the cap to spring automatically from the container.

In combination with a captive cap or closure adapted to be screwed upon a screwed nozzle, of a bifurcated spring member rotatably secured to the cap, and an element to which the screwed nozzle is secured, said element having spaced apertures therein, the free ends of the bifurcated spring member being adapted to engage with said spaced aperture whereby the limbs of the bifurcated spring member are sprung apart under strain so that when the cap is completely unscrewed from the nozzle the limbs move to a free position to relieve the strain and cause the cap to spring automatically from the nozzle and expose the opening therein.

l. In combination with a captive cap or closure adapted to be screwed on a screw threaded nozzle, of a bifurcated springmember, said spring member having a loop at one end thereof, said loop being rotatably secured to said cap, and spaced apertured anchoring means connected to said container, said apertures being adapted to have the free ends of the bifurcated spring member engage therewith for the purpose of securing said free ends, said apertures being so disposed that the limbs of the bifurcated spring member are sprung apart under strain so that when the cap is completely unscrewed from the nozzle the limbs move to a free position'to relieve the strain and cause the cap to spring automatically from the nozzle and expose the opening therein.

5. In combination with a captive cap or closure and container upon which the cap is adapted to be screwed, of a bifurcated spring member rotatably secured to the cap, and anchoring means connected to said container, said anchoring means having spaced holes therein, the free ends of the bifurcated spring member being engaged with said holes, the plane of the holes being different to the direction of the limbs of the bifurcated spring member so that when the cap is in the closed position the bifurcated ends of the spring member will be under strain and when the cap is completely unscrewed from the container the limbs of the spring member move to a free positionto relieve the strain and cause the cap-to spring automatically away from the end of the container.

6. In combination with a captive cap or' closure adapted to be screwed upon a screwed nozzle, of a bifurcated spring mem ber rotatably secured to the cap, and an element to which the screwed nozzle is secured, said element having spaced apertures therein, the free ends of the bifurcated spring member being adapted to engage with said spaced apertures, the plane of the apertures being different to the direction of the limbs so that when the cap is screwed on to the nozzle the limbs of the spring member will be under strain and when the cap is completely unscrewed from the nozzle the limbs of the spring member move to a free position. to relieve the strain and cause the cap to spring automatically away from the end of the nozzle.
